Abstract: PURPOSE:To obtain a high coupling efficiency when coupled with a singlemode fiber and absorb light leaked from an active layer to restrict laser oscillation, by coupling an absorption layer to the entire side surface, except for a light emitting end surface, of an active lay with reduced width and constituting a current blocking layer including this absorption layer. CONSTITUTION:An n-InP layer 4 is etched with a 2 deg.C etchant of (HCl+H2O), a P-InGap layer 3 is overetched with a liquid mixture of K3Fe(CN)6, KOH and H2O so as to reduce its width to 2-5mum to form an active layer. Again a p-Inp layer is etched with the 2 deg.C (HCl+H2O) etchant so as to leave the p-InP layer 2 on the entire surface of a p-InP substrate 1. Then an SiO2 film 5 is removed with a HF liquid to form a double-hetero junction structure consisting of the active layer and two clad layers pinching it. The projections of an n-InP layer 2 are removed by a liquid phase epitaxial growth method, on which an n-InP layer 6, p-InGaAsP layer 7 and p-InP layer 8 are grown in that order to form a block layer.

Abstract: PROBLEM TO BE SOLVED: To provide the exchange whose transfer service is improved. SOLUTION: When a terminal A (for voice) 201 of an ISDN extension interface 21 registers transfer registration, its attribute and transfer destination are registered. When a call comes in the interface 21 whose transfer is registered, in the case the attribute (e.g. for voice) included in call reception information is the same as the attribute (for voice) at the transfer registration, the call is transferred to a transfer destination terminal F (for voice) 206.

Abstract: PURPOSE:To prevent the running ability of an engine from being deteriorated due to discharge of unnecessary fuel, by disposing a change-over valve in an inner vent passage communicating between the inlet port and the float chamber in a carburettor so that the change-over valve is opened only when supercharged pressure is abnormally raised, to introduce the atmospheric pressure into the float chamber. CONSTITUTION:When the pressure PT of intake-air in a carburettor 1 is high just before deceleration of a vehicle, a throttle valve 2 is abruptly closed to increase the pressure PIM of intake-air pipe so that the pressure PA in a venturi section 3 is abruptly lowered. However, since a float chamber 4 is communicated to the outside thereof through constriction given by a main jet 5 and an acceleration pump nozzle 6, the pressure of the float chamber 4 is maintained high for a while. Further, in the inner vent passage 13 there is provided a change-over valve mechanism composed of a valve seat 14 and a valve element 15 so that the valve side outlet port thereof is opened to the passage 13 and as well the other end thereof is opened to the atmospheric side. With this arrangement if supercharged pressure which is effected from the inlet port of the carburettor 1 exceeds a predetermined value, the valve 15 is opened so that the pressure of the float chamber 4 is made near to the atmospheric pressure.
